a"? whom it Q176 concern ii; known is at l, JOHN F. eans, a

oi the United States, residing at nnm, in the county of St. Joseph andfi tate oi hlichigan, have invented eernew and useful linii'irovementsin 'eainiiuperhcate' oi which the following is .t :meciliearion,reference being had there-- in to the accompanying drawing".

invention relates to certain new and ui-elul im', ro .'cn1cns in steamsuperheatcrs, he object being to provide superheater winch run bereadily placed in position wiihin the smoke box oi an ordinary boilerand adjusted so that the tire tubes ihereof will be in alinemenl; withthe fire tubes of lhc 1T.

finotl =r object of my ii'ivention is to provide a superhcater which issupported within the smoke box by a series of positioning readily postioned within the smoke box or removed "Lin-re ron; to make thenecessary repairs.

another object of my invcntionlis to prosuperheanir which issoconstri'ieted h at. priming is prevented so as to eliminate the use oi apriming valve.

nother object of my invention is to proa snperheai'er in the form of adrum having inlet pipe extending 't'rom the dome of the boiler 01? agreater size than ihe ouilet extending to the engine so as to preventlhe engine drawing steam from the single-heater.

Another a nil "further object n"- my inveniion to provide a super-heaterwhich is exrcedii'igziy c cap and simple in construction and one whichis provided with a central partition having a series of openings adjacent iis lower end so as to causethe steam entering the some to passdownwardly over a series of fire tubes and then, upwardly over a seriesoi fire tubes so as to beat the same before the same is conveyed to theengine.

lithe/r and further objects and advantages o the invention will behereinafter set forth m the novel. features thereof defined by theappended claims.

in the drawings: Figure 1 is a longitudinal section through a boilershowing the superheater in position within the smoke box, Fig. 2 is asection taken on line 2 E2 of Fig. 1, and Fig. 3 is a detail perspectiveview of the partition.

Like numerals of reference refer to like parts in the several figures ofthe. drawings.

in the drawings, 1 indicates an ordinary form of boiler having a seriesof fire tubes 2, and the usual dome 3, to which is connected a steampipe 4, for conveying the steam to the super-heater as will behereinafter fully described, said boiler having a smoke box 5, providedwith the usual smoke stack.

My improved construction of superheater comprises a drum 3, having aseries of fire tubes 7, adapted to be placed in alinement with the .iretubes 2 of the boiler, so as to allow the heat units to pass through thefire tubes thereof, so as to thoroughly heat the steam passing throughthe superheater. 'lhe superheater is provided with an inlet 7, to whichis connected the steam pipes,- by a suitable coupling member, and withan outlet 8, to which connected a'pipe 9,"

adapted to extend to the engine. The pipes l and S) extend throughsuitable apertured bosses formed in the sh'cllof the smoke box, and thepipe 4 is of larger diameter than the pipe 9 so that the supply of steamto the slmerheater will be greater than the exit of the steam therefrom.The drum (3, form ing the superheater, is provided with a centralpartition 10, having a series of openings H adjacent its lower end,through which the steam entering the compartment 12, passes into thecompartment 13, so as to cause the steam to pass downwardly over theseries of fire cubes in its passage through the compartment 12 and upover the series of fire tubes in its passage through the compartment 13.

The shell of the smoke box is provided with a plurality of bosses,provided with threaded bores 14:, in. which are mounted positioningscrews 15 which have their inner ends loosely mountedv in sockets 16,formed in the shell ot the superheater so that by adjusting" the pins,the superheater can be adjusted in the smoke box so that the fire tubesthereof will be in alinement with the fire tubes of the boiler, spacingpins also being employed for holding the superheater spaced from thetube sheet of the boiler, said pins being mounted within sockets formedrespectively within the tube sheet and superheater as clearly shown inFig. 1.

It will be seen that by adjusting the positioning screws 15, thesuperheater can be so' positioned withirithe smoke box so that, theflues thereof Will be in alinement with lbhe fines of the boiler, andthat the same will be firmly held in adjusted position and in such amanner that by loosening the positioning screws the superheater can bemoved out of the way in the smoke box so that any necessary repairscanbe made to theboiler.

From the foregoing description it will be seen that I have provided asuperheater for aboiler comprising a drum mounted within a smoke boxupon a series of positioning screws, and havinga pair of compartments,one compartment being provided with an inlet adjacent its top, and theother with an outlet adjacent its. top, said compartments communicatingwith each other adjacent the bottom so as to cause the 'steam to travelaround the fire tubes in its passage through the superheater, wherebythe same will be thoroughly heated so as to prevent water from beingcarried by thesteam to the cylin- 1 der of the engine 1 What is claimedis I v 1. The combination with a steam boiler for a smoke box, of bossesformed on said box provided with threaded bores, positioning screwsworking in said bores and a drum provided with sockets'arranged withinsaid smoke box adapted to receive the ends 'of said positioning screws.

I having fire tubes andv a smoke box, ofa

drum provided with fire tubes arranged within said smoke box, said drumbeing provided with sockets means for spacing said drum from the tubesheet of the boiler, and

positioning screws carried by the casing of the smoke box working withinsaid sockets. 4. The combination with a steam boiler having fire tubesand a smoke box, of a superheating drum disposed within said smoke boxhaving horizontally disposed fire tubes, said drum being provided withsockets, means for spacing said drum from the tube sheet of the boiler,and a plurality of positioning screws extending through the wall of thesmoke box having their ends mounted within said sockets for positioningsaid super-heater within said smoke box.

5. The combination with a steam boiler having horizontally disposed firetubes and a smokebox at one end thereof, of a drum disposed in saidsmoke box provided with horizontally disposed fire tubes, a series ofindependently adjustable supports for supporting said drum in said smokebox with the fire tubes thereof in alinement with the fire tubes of theboiler, said drum having a vertically disposed partition arrangedcentrally therein between the fire tubes thereof, the ends of saidpartition being bent outwardly in opposite direction to provide flangesfor securing said partition within said drum to the top and bottomthereof,

"said partition being provided with a series of openings adjacent thebottom affording communication between the two compartments, formed bysaid partition, one of said compartments being provided with an outletextending from the upper end thereof and the-other compartment beingprovided with an inlet of a larger diameter than the outlet.

In testimony whereof I aflix my signature in presence of two witnesses.
